Abstract

This review examines the role of biochar as a carrier for plant growth-promoting bacteria (PGPB) in the phytoremediation process of pesticides. It begins by exploring the properties and performance of biochar, including its production processes and physical and chemical characteristics. The review then discusses the roles and mechanisms of PGPB, such as nitrogen fixation, phosphate solubilization, and phytohormone production, emphasizing how these bacteria can enhance plant growth and tolerance to environmental stresses while aiding in pesticide degradation. The suitability of biochar as a carrier for PGPB is highlighted due to its porous structure, surface chemistry, and ability to create microbial habitats. The interactions between biochar, PGPB, and plants that can enhance phytoremediation efficiency are examined. The review additionally identifies the related challenges and limitations, suggesting areas for further research to develop practical applications. This review aims to provide a comprehensive overview of the potential of biochar as a carrier for PGPB in improving phytoremediation outcomes, explicitly addressing the lack of prior reviews on this topic and highlighting broader implications for sustainable remediation.

生物炭作为植物促生菌的载体在植物修复农药中的应用

本文综述了生物炭作为植物生长促进菌（PGPB）载体在农药修复过程中的作用。它首先探索生物炭的特性和性能，包括其生产过程和物理和化学特性。在此基础上，综述了PGPB在固氮、增磷和产生植物激素等方面的作用和机制，强调了这些细菌如何促进植物生长和对环境胁迫的耐受性，同时帮助农药降解。由于其多孔结构、表面化学性质和创造微生物栖息地的能力，生物炭作为PGPB载体的适用性得到了强调。研究了生物炭、PGPB和植物之间的相互作用对提高植物修复效率的影响。该综述还指出了相关的挑战和限制，提出了进一步研究以开发实际应用的领域。这篇综述旨在全面概述生物炭作为PGPB载体在改善植物修复结果方面的潜力，明确解决了这一主题之前缺乏的综述，并强调了可持续修复的更广泛意义。
